How Date of Birth Is Recorded on Aadhaar
UIDAI, the authority that manages Aadhaar, records date of birth in one of three ways. A verified date of birth includes the full day, month and year and is supported by a birth certificate or other official document. A declared date of birth includes only the year of birth because no documentary proof was available. An approximate date of birth is estimated by the enrollment officer when no documents are available at all. The Aadhaar card itself displays the date in DD/MM/YYYY format when verified, or just the year when declared.
What to Do if Your Aadhaar Has Only Year of Birth
If your Aadhaar shows only a year without a specific date, your date of birth is treated as January 1 of that year for most administrative purposes. This can have practical implications for age calculations at threshold dates. If you have birth records that were not submitted during Aadhaar enrollment, you can update your date of birth through the UIDAI portal by submitting valid documentary evidence. This update can only be done once.
Documents Accepted for Date of Birth Proof on Aadhaar
UIDAI accepts a range of documents as proof of date of birth including birth certificates issued by municipal authorities, school leaving certificates, passports, and PAN cards that show date of birth. Hospital birth records are sometimes accepted with additional verification. For older individuals who were born before formal registration was common, alternative documents like school records may be the only option.
Using Aadhaar Age for Financial and Government Services
Aadhaar-verified age is accepted for bank account opening, EPF and NPS account management, income tax filing, government welfare schemes, senior citizen benefits, and many other purposes. When applying for senior citizen benefits that begin at age 60, the date of birth on your Aadhaar is the reference used by most government departments. Having an accurate and verified date of birth on your Aadhaar is therefore practically important.

Protecting Aadhaar Information
While your date of birth from your Aadhaar is used for many verification purposes, be cautious about sharing your full Aadhaar number unnecessarily. Use the masked Aadhaar option, which shows only the last four digits, when sharing with entities that do not require the full number. UIDAI regularly issues advisories about appropriate sharing of Aadhaar information to prevent misuse.
